upgrading issues on Mac

When I click the system preferences, software update isn't there. I am trying to update to a newer OS (I am currently using High Serra) but when I try I can't find anywhere to upgrade. When I go into the the apple store, Big Sur will not download, even though I have enough memory. What do I do now?

iMac Line (2012 and Later)

Incompatibility is the Culprit:

What is the model of your Mac? Big Sur is incompatible with any 2012 Mac model, whatsoever. See here: macOS Big Sur is Compatible with these Computers - Apple Support

Software Update did not appear as a System Preferences panel until macOS Mojave 10.14.

Prior to that you have to go to Apple menu > About This Mac > Software Update...


With that in mind, here is some compatibility info for several macOS versions newer than High Sierra:


macOS 10.14 Mojave is compatible with the Macs listed here:

macOS 10.15 Catalina is compatible with the Macs listed here:

macOS 11 Big Sur is compatible with the Macs listed here:

The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.


With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install.  For Best results use Safari to commence the download as Others may not work.


Safari will open. redirect and open the Apple Store where the download can commence.


Make Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS


Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina & Big Sur supports only 64 bit and there is no workaround.


Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.


Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation
